Li-cellulose ethers, tse kang methyl cellulose (MC) le hydroxypropyl methyl cellulose (HPMC), li sebelisoa haholo lihlahisoa tse entsoeng ka samente ka lebaka la ho boloka metsi hantle, ho sebetsa le ho khomarela thepa. Leha ho le joalo, ts'ebetso ea li-cellulose ethers lihlahisoa tsa samente e ka angoa ke lintlha tse fapaneng, ho kenyelletsa mofuta le tekanyo ea cellulose ether, mofuta le tekanyo ea samente, maemo a pheko le maemo a tikoloho. Ka hona, ke habohlokoa ho laola ka katleho ts'ebetso ea cellulose ethers lihlahisoa tsa samente ho netefatsa boleng bo tsitsitseng le ts'ebetso.

1. Khetho ea Mofuta oa Ether ea Cellulose le Tekanyetso

Khetho ea mofuta oa cellulose ether le litekanyetso li bohlokoa ho laola ts'ebetso ea li-cellulose ethers lihlahisoa tsa samente. Li-ether tse fapaneng tsa cellulose li na le thepa e fapaneng, 'me khetho ea mofuta o nepahetseng oa cellulose ether e itšetlehile ka litlhoko tse khethehileng tsa kopo le ts'ebetso. Ka mohlala, HPMC e atisa ho sebelisoa ho li-adhesives tsa lithaele ka lebaka la ho boloka metsi hantle le thepa ea ho khomarela, ha MC e atisa ho sebelisoa ho renders le mortars ka lebaka la ho sebetsa ha eona hantle le thepa ea ho boloka metsi.

Tekanyo ea ether ea cellulose e boetse e phetha karolo ea bohlokoa ho laola ts'ebetso ea eona lihlahisoa tsa samente. Tekanyo e loketseng ea cellulose ether e itšetlehile ka lintlha tse fapaneng, ho kenyelletsa mofuta le litekanyetso tsa samente, bokhoni bo lakatsehang ba ho sebetsa le ho boloka metsi, le maemo a tikoloho. Ka kakaretso, tekanyo ea cellulose ether e tloha ho 0.1% ho ea ho 2% ka boima ba samente, ho itšetlehile ka litlhoko tse khethehileng tsa kopo le ts'ebetso.

2. Ho lumellana le Cement

Ho lumellana ha cellulose ether le samente ho bohlokoa ho laola ts'ebetso ea eona lihlahisoa tsa samente. Ho eketsoa ha cellulose ether ho samente ho ka ama nako ea ho beha, matla le ho sebetsa ha samente, ho itšetlehile ka mofuta le tekanyo ea cellulose ether le mofuta oa samente. Ka hona, ho bohlokoa ho netefatsa ho lumellana ha cellulose ether le samente ho netefatsa boleng bo tsitsitseng le ts'ebetso.

Ho lumellana ha cellulose ether le samente ho ka hlahlojoa ka ho etsa liteko tsa ho lumellana, tse kang tlhahlobo ea Vicat, teko ea pele le ea ho qetela ea nako ea ho beha, le teko ea matla a khatello. Liphetho tsa liteko tsena li ka fana ka leseli la bohlokoa mabapi le ts'ebetso ea cellulose ether lihlahisoa tsa samente mme li ka sebelisoa ho ntlafatsa mofuta le litekanyetso tsa cellulose ether.

3. Phekolo Maemo

Maemo a pheko a lihlahisoa tsa samente a ka ama haholo ts'ebetso ea cellulose ethers. Maemo a pheko, ho kopanyelletsa le thempereichara, mongobo, le nako ea ho folisa, a ka ama metsi a samente le ho sebetsa ha cellulose ethers. Maemo a nepahetseng a ho folisa a ipapisitse le ts'ebeliso e khethehileng le litlhoko tsa ts'ebetso.

Mohlala, ka har'a likhomaretsi tsa lithaele, maemo a nepahetseng a ho folisa hangata ke mocheso oa kamore o nang le mongobo o itekanetseng le nako ea ho folisa ea lihora tse 24 ho isa ho tse 48. Ho li-renders le lirekere, maemo a nepahetseng a ho folisa a ka fapana ho latela ts'ebeliso e khethehileng, empa hangata a kenyelletsa mocheso o phahameng le linako tse telele tsa ho folisa.

4. Maemo a Tikoloho

Maemo a tikoloho, joalo ka mocheso, mongobo, le ho pepesehela lik'hemik'hale kapa lintho tse silafatsang, le tsona li ka ama ts'ebetso ea li-cellulose ethers lihlahisoa tsa samente. Mohlala, ho pepesehela mocheso o phahameng kapa mongobo o tlase ho ka ama thepa ea ho boloka metsi ea li-cellulose ethers, e lebisang ho fokotseng ho sebetsa le ho khomarela. Ho pepesehela lik'hemik'hale kapa lintho tse silafatsang ho ka boela ha ama ts'ebetso ea cellulose ethers, e lebisang ho fokotseng matla kapa nako e telele.

Ka hona, ho bohlokoa ho nahana ka maemo a tikoloho nakong ea ts'ebeliso le ts'ebeliso ea li-cellulose ethers lihlahisoa tsa samente. Ho boloka le ho tšoara cellulose ethers ka mokhoa o nepahetseng ho ka boela ha thusa ho boloka ts'ebetso ea bona le ho netefatsa boleng bo tsitsitseng.

Qetellong, taolo e sebetsang ea tšebetso ea li-cellulose ethers lihlahisoa tsa samente e hloka hore ho nahanoe ka hloko lintlha tse fapa-fapaneng, ho akarelletsa le mofuta le tekanyo ea cellulose ether, ho lumellana le samente, maemo a phekolo le maemo a tikoloho. Ka ho ntlafatsa lintlha tsena, hoa khoneha ho finyella boleng bo tsitsitseng le ts'ebetso ea cellulose ethers lihlahisoa tsa samente, e leng se lebisang ho ntlafatso ea ts'ebetso, ho boloka metsi le thepa ea ho khomarela.
